Application October 18, 1948, Serial No. 55,126

4 Claims.

This invention has to do with a method for applying a form member to a beam, or the like, and it is a general object of the invention to provide a. simple, practical method for applying a board or member such as the base or bottom of a form to a part such as a beam or element 01 a building.

'The present invention is related, generally, to a method for effectively applying parts of a form construction, such as are set forth in my copending application entitled Form Construction, Serial No. 29,073, filed May 28, 1948, to a beam or structural member such an an I- beam, or the like, so that the form member is accurately and dependably supported beneath the beam.

A further object of the invention is to provide methods for effectively handling hangers included in a form or forming a part of a form, so that they are accurately and securely attached to a beam such as an I-beam, or the like with out the use of spacers such as are commonly used to locate form parts relative to a beam. By the present invention benders are provided for applying hangers to a beam so that the hangers are snugly and accurately applied or crimped onto the beam, so that they are effectively secured thereto.

The various objects and features of my invention will be fully understood from the folof the hangers connected with the bottom andin position at the beam some ready for engagement with the beam and one in the course of being made ready to engage the beam. Fig. 3 is a plan view of a portion of a structure such as is shown in Fig. 2, showing the upper end portion of one hanger arranged to extend across the beam'and the other in the process of being swung across the beam. Fig. 4 is a view taken transversely of the beam showing a hanger in 'll on Fig. 5. Fig. 8 is an enlarged detailed transverse sectional view taken as indicated by line 8-8 on Fig. 5. Fig. 9 is a plan view taken as indicated by line 9-9 on Fig. 5. Fig. 10 is an enlarged view of apparatus shown in Fig. 2,

showing it in a more fully operated position, and

Fig. 11 is a detailed sectional view taken as indicated by the line ll-H on Fig. 10.

The present invention can be used to advantage'in applying part of the form construction, such as I have hereinabove referred to, to an I-beam, or the like, and for purpose of example the invention will be described in connection with or as being used to apply the bottom or base of a form to an I-beam by means of hangers which project upwardly from the bottom and are engaged with or applied to the upper flange of the beam. In the drawings the form member or bottom is indicated at A and several like hangers B are shown in connection with the bottom. The beam C to which the elements A and B are secured is shown as an'ordinary I- beam having a vertically disposed central web I!) and like horizontally disposed upper and lower flanges H and I2.

The methods of the present invention are applied successively to the hangers B and it is preferred that the several hangers be alike and therefore I will describe but one hanger and the operations that are performed thereon, it being understood that such description is applicable to each and every one of the hangers.

The hanger B shown in the drawings is formed of a length of rod or bar such for example as iron or mild steel, and it has a deformable straight, elongate central or body portion 15, a lower end portion l6 and an upper end or head portion IT. The lower end portion iii of the hanger may be secured to the bottom A of the form in any suitable manner. In the case illustrated the bottom A is shown as involving an elongate fiat board 2!) with a fiat top 2| and a fiat bottom 22. The lower end portion I6 of the hanger passes through an opening in the board and is hooked around a cross arm 24 engaged under the board in the manner clearly shown throughout the drawings. With the hanger thus initially prepared or applied to the bottom A the body portion l5 of the hanger projects upwardly from the board 2%) and in its original form the upper end portion ll of the hanger is straight and is an integral continuation of the body portion [5 of the hanger.

In accordance with the present invention the first operation performed upon the hanger is bending the hanger to establish a right angle corner '-betweenthe body portion Iii and the upper endzpdrtion H, and ordinarily it is most convenient to make this bend so that the upper end portion ll of the hanger extends parallel with the beam and the bend is so located that'the lower or bottom edge portion 23 of the portion I! is in the plane of or is flush with the top 21 of the upper flange H of the beam. In practice the hangers are applied to the bottom Aeso that when the parts are initially positioned at the beam the hangers extend upwardly at opposite sides of the beam at or close to the edges 23 and 29'of the flange H.

' The bender provided by the present invention for making the right angle bend at 25 between the body and upper end'portion of the hanger preferably includes an elongate frame 38* with a side channel "3! for reception of the body portion I5o f thehanger-and a lever'32 operating relative to the frame. The lever is preferably joined to the upper end of thefrarne by pivot pirr33 and has a head portion adjacent the point that is pivotallyconnected to. the frame,

which head portion is' adapted" to engage the end portionl'l of the hanger immediately. above the upper 'endof the frame 3!} in such'rnanner as to bend the end portion of the hanger'over the upper end or the frame, as indicated in Fig. 2 of the drawings. A handle 35" projects from the head 3ll ofthelever andis of" such form and length'as to be readily engagedby' the operator so that the head' can be easily swung'in such manner as to effect'the desired bend'in the'hangeri Thebender provided for establishing the bend between the body l5 andend' or head portion i1 preferably" includes an adjustable stop' or leg 36 that dependsfrom the frame to engage or stop against'the 'top 'or upper side2l of' the bottom A. In the construction illustrated the stop {leis slidably carried in a guide opening 31 in the frame 36 and a set screw 38'is pro vid-ed for making the stop secure'in the desired position. As the bender is usedthe body [5 may be temporarily deflected slightly away from thebeam.

It will be immediately apparent from Figs. 2 and 10 of the drawings how the bender provided for making theinitial'bendin'the hanger may be easily andquickly applied to the hanger so that the body portion thereof enters the'channelgt l while the stop 36 rests on thetop' of. the

bottom member A. With the bender'thus-posF some relative to the hanger simpleswinglng' or turning of the handle in the direction indicated by the arrow 'in Fig. '2' makes the desired right angle bend'br corner25. The hanger is shown initially bent in the'desired'm'anner in Fig: 10 of the drawings where the lower'or bottom edge portion Z'G'of the end portion i? of the hanger is shown flush with the top 2'! of the beam flange ll while theend portion I1.

extends parallel with the beam adjacent the edge 28 thereof. The stop makes it unnecessary to use spacers between the bottom A and the beam.

The next operation performed upon the hanger is twisting of the body l5 of the hanger so that the end portion ll horizontally disposed, as shown in Figs. 2 and 10, is swung from a position parallel with the beam to a position transverse of the beam in engagement therewith and extending across the beam as shown at X in Fig. 3. At Y in Fig. 3 the end portion ll of a hanger is shown in the course of being swung to a-position'transverse of the beam. To thus positionthe upper end portion ll of the hanger transversely of the beam no tools or equipment are required, since the end portion ll of the hanger in androf; itself forms a convenient lever by which the desired torque can be applied to the body I5 in order to cause permanent distortion thereof; -When'the upper end portion ll of the hanger has been moved or swung to the transverse position its end or tip portion 46 projects from the edge of the beam opposite to the edge engaged by the body of the hanger. For instance, as. shown inFig. 4, whenithebody of the hanger engagesorabuts the. edge28of the-beam flange: It the tip 40 of the hanger portion IT projects outward. from or beyond 'the edge 29 of flange:

'The next operation, in accordance with the present invention, is crimping of the tip portion 49 'of'. the" hanger so that it is. engaged around the edgezofthebeam at. the edge 29 of the beam. Inaccordance withi-thezpreferred form of the-inventibnithfifi portion. Mi-isz so crimpedor bent asi to. first extend down past the-edge 29 and thereafter extend back" or inward under the edge portion of the beam' to a position such as is illustrated' in Fig.- Gof the drawings. The crimping or bending of the tip 40 of the hanger is performed while the body portion i5 of the hanger is held tight against the opposite edge of the beam.

The bender provided by the present invention to "clamp the body l-5 to the beamand bend the tip 40. of thehanger is shown in Figs. 4, 5, 6, '7, 8 -and 9 of thedrawings and in the form illustrated it involves, generally, an elongate shank 50 carrying opposed clamp jaws 5| and 52, operating means 53 for operating the clamp jaws relative to each other, and a lever 54' carried by and operable reative to the shank 50 to efiect the desired bending" of the tip-4U of the hanger.

The shank 5i] is shown as an elongate bar and one of the-jaws is shown fixed on-the bar while the. other is shiftable along the bar. The jaw 5! which engages the edge'of the beam around which the tip of the hanger is to be bent is preferably fixed 'on one end-of the shank 58 while the jaw 52, which engages the opposite edge of the beam is slidable on the beam. The jaw 52 is shown provided with'a guide portion 55 slidably engaged with the'shank 5D.

In accordance with the present invention the ings. "The. jaw 5 hasone or more fingers 58,

opposing the fingers 51 ofjaw 52 so that the upper flange ll of the beam is effectively gripped or embraced when the structure is applied thereto, as shown in the drawings.

The, operating means 53 provided for movin the jaws relative to each other is preferably such as to operate the jaws so that they crimp or grip the upper flange of the beam in the desired manner.

In the case illustrated the operating means 53 is a toggle mechanism involving pivotally connected links 60 and BI, a handle 62 projecting from one link, and an adjustable carrier 63 supported by the shank 50 and supporting one of the links. In the case illustrated link 60 is pivotally connected to the carrier 63 while the link 6|, which is pivoted to link 60 is pivotally connected to the jaw 52. The carrier 53 is adjustable along the shank 50 and a set screw 65 is provided for setting the carrier in any desired position on the shank. Through this construction the operating means can be adjusted to accommodate beam flanges of various widths and the mechanism is such that it can be set to apply great force to the jaws by suitable operation of the handle 62.

The lever 54 is carried by or on a pivot pin 10 at the end of the shank 50 which carries the jaw 5|. The lever is shown as involvin a handle II, a lug 12 projecting laterally from the handle and pivotally connected to the shank 50, and a head 13 projecting from the handle at the point where the ug is located and en ageable with the tin All of the hanger. The head 13 of the lever 54 is so proportioned and related to the other elements just described that it enga es the upper side or up er ed e portion of the tip 4!! as the tip initially projects from the beam. When the lever or handle In is swung in the direction indicated bv the arrow in Fi 5 the head 13 moves do n de ressing the tip If! as shown in Fig. 5, and it finall mo es to a position where it bends the tip 40 under the flange of the beam, as shown in Fig. 6.

In the preferred form of the in ention the head 13 is ad usta le or s iftable relative to the lu l2 and handle I! so that it can be arranged to en a e the tip 4!! at various points or in various manners. as shown in Figs. 5 and 6 of the drawings. In the particular case illustrated the head 13 has an e tension 80 slidablv carried on the hande l3 adiacent the lug 12 and throu h this construction the head can be positioned to proiect a substantial d stance from the lug as shown in Fig. 6, where the mechanism has considerable levera e over the tip 40 and seats it tight against the flange of the beam or it can be arranged in a position such as is shown in Fig. 5 where it projects but a limited distance, in which case it mav en age the tip 40 at or close to the point where the tip is bent around the edge of the beam, in order to initially bend the tip over the ed e of the beam and effect a snug engagement of the tip with the beam.

From the foregoing description it will be apparent that the method provided by the present invention involves but few simple operations which, when successively performed upon the hanger, establish the hanger on a beam with the upper end of the body of the hanger tight against one edge of the beam while the tip of the hanger is crimped or bent tightly around the other edge of the beam. It will be understood from the drawings how the invention has provided simple apparatus by which the operations or bends required are easily and accurately formed, to the end that by few simple operations a form member such as the bottom A of a form may be applied to a beam to be accurately located relative to the beam, while at the same time it is eifectively secured to the beam in a most secure and dependable manner.

Having described only a typical preferred form and application of my invention, I do not wish to be limited or restricted to the specific details herein set forth, but wish to reserve to myself any variations or modifications that may appear to those skilled in the art and fall within the scope of the following claims.
